| Abstract: |
| With the mature seed of wild Chimonanthus salicifolius Hu as raw material, the seed oil was obtained by ultrasound-assisted extraction. The physicochemical properties, VE content and fatty acid composition of wild Chimonanthus salicifolius Hu seed oil were determined. The antioxidant activities of wild Chimonanthus salicifolius Hu seed oil were also evaluated by scavenging capacity against ABTS free radical and metal ions chelating ability. The results showed that the acid value, iodine value, peroxide value, saponification value, moisture and volatiles, relative density(20 ℃), refractive index (20 ℃) and vitamin E content of wild Chimonanthus salicifolius Hu seed oil were 2.28 mgKOH/g, 109.47 gI/100 g, 2.03 mmol/kg, 185.81 mgKOH/g, 0.82%, 0.927 5, 1.467 3 and 109.27 mg/kg, respectively. Twenty-two kinds of fatty acids were identified from wild Chimonanthus salicifolius Hu seed oil including eight kinds of saturated fatty acids (24.28%) and fourteen kinds of unsaturated fatty acids (75.37%). The main fatty acids were linoleic acid (55.60%), palmitic acid (20.26%), oleic acid (8.08%), and 10,13-octadecadienoic acid (8.02%). The wild Chimonanthus salicifolius Hu seed oil had good antioxidant activities, and its scavenging capacity against ABTS free radical was better than that of grape seed oil, while the metal ions chelating ability was weaker than that of grape seed oil. |
